At a dizzying height of 553.3 meters (1,815.3 feet), the slender form of the CN Tower rises high above the city skyline. One of the world's tallest towers, unmatched by any freestanding structure in the Western Hemisphere, this stunning landmark was built in 1967 by the Canadian National Railway to serve as a communications and observation facility. At that time, this man-made pinnacle was unsurpassed by any other across the world and remained as such until 2007. The Look Out Level of CN Tower grants spectacular view of the city for miles around from a height of 346 meters (1,136 feet), while the SkyPod sits an additional 33 storeys above for a unique perspective of the world. The EdgeWalk, another of the tower's attractions, is the world's highest hands-free walkway. Not for the faint hearted, walking along the open-air walkway is an experience like none other. The EdgeWalk is perched on the roof of the 360 Restaurant where dinner is served in full view of Toronto's twinkling skyline.
